To aZZ whom it may concern;

Be it known that I, RICHARD B. CHARLTON, a citizen of the United States,residing a't'lliilwaukee, in the county ofMilwaukee and State ofWVisconsin, have invented certain new and useful Improvements in Rolls;and I do h'ereby declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the artto which it appertains to make and use the same,reference being had to the accompanying drawings,and to thecharacters ofreference marked thereon, which form a part of this specifica tion.

This invention relates to rolls for forming that class of railwayfish-plates or rail-joint connections represented by the one shown inPatent No. 427,017, of April 29, 1890, andhaving a V-shaped extensionfor inclosing the base-flange of the rail. The objects of the presentinvention *are to provide such rolls having a pass which will roll abarto be cut up into such fish-plates and deliver the same straight andtrue, to prevent buckling of the bar and its delivery from the rolls ina crooked and twisted condition; because'of the great difierence inradialdistance from the center of the rolls to different points on theWalls of the pass, to provide a finishing-pass which will bend up thebase flange of the fish-plate bar without roughening itby a grindingaction, to securea pass havinga portion of its walls rotatableindependent of the other portions, and to obtain other advantages andresults, some of which may be referred to hereinafter in connection withthe description of the working parts;

The invention consists in the improved rolls for rolling railwayfish-plates or joint connections and in the arrangements andcombinations of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like characters ofreference indicate corresponding parts in each of the several figures,Figure 1 showsin elevation the preparatory or roughing set of a train offish-plateforming rolls, and Fig. 2 is the finishing set, the middleroll of said finishing set being partly in section to more clearly showmy invention' applied .thereto. Figs. 8 and 4 are views of a certaincollar from itsinner and outer sides, respectively; and Fig. 5 shows insectionsaid collar in place on the roll-spindle. In said drawings, 0 b19 indicate the top, bottom, and middle rolls, respectively, of a set ofroughing or forming rolls, providing betweenthemselves two alternatingseries of passes 1 2 3 4 5 and 1 2 3" 4 5, respectively, each adapted togradually shape a bar of iron to approximately the cross sectional formrequisite for fish-plates to be cut therefrom. The bar 'is then reducedto more exact proportions by a pass 6 (or 6) of the finishingrolls 0 0'0 (shown in Fig. 2,) and finally the flange adapted to form the basemember of the fish-plate is bent by a finishing pass 7 (or 7*) intoproper angular relation to the foot-member flange. The projection d ofthe pass enters between said flanges to form the angular space oropening which afterward receives the base-flange of'the railinthecompleted fishplate.

i The passes of thetop finishing-roll c are formed on or by rings orsleeves e e 6 &c.,

fittipg icely on the spindlef ofthe roll and held to rotate-therewithbyakeyor spline g, a nut h being'screwed'on the spindle to press saidrings or sleeves against the shoulder 2 and prevent longitudinaldisplacement. The bottom roll is similarly formed, and it has beencommon to make the middle roll the same way, the objectoftheconstruction being to permit any particular sleeve when worn to bereplaced without abandoning the entire roll.

The final or .finishing pass 7 (or 7*) of the rolls forms between 'aside wall j of the groove on the middle'roll and the projection d on thecooperating roll a space it, which is adapted to bend thebase member ofthe fish-plate into final'edgewise position at right angles to therolls. In this position the, great difference in distance of the bottomand outer parts, respectively, of said space 70 from'the center ofrotation causes a great difference of speed between said two points, andthe tendency has been to buckle the bar and deliver it in a crooked passwere rigid with respect to each other and the roll-spindle. Moreover, agrinding action of the side wall j was produced on the bar, whichroughened the bar and rapidly were away the side of the pass.

By my improved construction I form the ring or sleeve E of the middleroll and which forms the side wall j of the finishing-pass loose uponthe roll-spindle f and loose with respect to the sleeve E and nut 72. onopposite sides of itself. This I accomplish, preferably, by the meansshown in the drawings, where the key or spline g, holding the rings orsleeves E E E, &c., on the roll-spindle, terminates short of the ring orsleeve E, said ring or sleeve being simply fitted neatly on the spindleand the nut h being screwed on said spindle outside the ring or sleeveE. Concentric annular grooves Z Z are cut in the adjacent faces of thesleeve E and next inner sleeve E and balls m inserted to reducefriction, and on the outer side of the sleeve E are similar grooves n 0,adapted to register with grooves n o in the nut h and form bearings forantifriction-balls p. The ring or sleeve E, which forms theright-angular wallj of the finishing-pass, is thus made free to adjustits rotary motion to the bar being delivered and a more perfect productis secured.

Having thus described the invention, what I claim as new is 1. A rollfor rolling metal, having in its periphery an annular pass-groove oneside wall of which is formed by a fixed portion of the roll and theother by a loose portion.

2. A roll for rolling metal, said roll presenting an annular peripheralpass-groove, and having an annular fixed flange forming one side wall ofsaid groove and a rotatably-loose ring or sleeve forming the other sidewall of the groove.

3. A roll for rolling metal, having two peripherally-projecting flangesforming a passgroove between themselves, one of said flanges being fixedand the other being rotatably loose.

4.. A roll for rolling metal, having a fixed annularprojection and arotatably-loose ring, said parts having their centers in the same axialline and being adapted to receive metal between themselves.

5. A roll for rolling metal, having at its periphery annular shouldersor projecting walls facing toward each other one of which is fixed andthe other rotatably loose with respect to the roll.

6. A roll for rolling metal, having peripherally-projecting annularshoulders or walls adapted to engage the metal in rolling, one of saidshoulders or walls being fixed and the other rotatably loose.

7. A roll, having a pass-groove, one side wall of which is fixed withrespect to the body of the roll, a ring or sleeve fitted loosely on thebody of said roll and forming the opposite side wall ofsaid pass-groove,and means for preventing longitudinal displacement of said ring orsleeve.

8. A roll, having a reentrant pass-groove disposed at or nearly at rightangles to the roll, a loose annular or transverse section of the rollforming one sidewall of said passgroove, and means for preventingdisplacement of said section longitudinally of the roll.

9. The herein-described. roll, comprising a body part presenting anoutwardly-projecting annular shoulder and having a spindle f, a ring orsleeve e, loose on said spindle and forming between itself and the saidshoulder a pass-groove, and a holding-nut h, screwed on said spindleoutside the sleeve.

In testimony that I claim the foregoing I have hereunto set my hand this12th day of June, 1901.
